Circle CCTP Cross-Chain Stablecoin Bridge to Arc Testnet

Live Circle CCTP Bridge Enabled
Domain ID: 26 (Arc Testnet)

Circle Cross-Chain Transfer Protocol (CCTP)

CCTP is a native burn-and-mint protocol built by Circle. It allows USDC to flow natively between chains without lock-and-mint wrappers. When bridging to Arc Testnet, the burned ERC-20 USDC from the source chain is minted directly on Arc as the native gas token, ensuring sub-second transaction finality.
